What Plentia stores in your browser, what for and for how long.
Draft pending legal review. It was structured and filled in with real product details by the person who builds it, who is not a lawyer. A lawyer reviews it before the first customer is charged.
This list comes from measuring the site and the dashboard in a real browser on 21/09/2026, not from what we believe they do. It also covers localStorage and sessionStorage, which the law treats the same as cookies: article 22.2 speaks of “data storage and retrieval devices in users’ terminal equipment”, not only of cookies.
| What | Where | What for | How long |
|---|---|---|---|
| plentia-idioma | Cookie and localStorage | Remembering whether you chose Spanish or English | One year |
| plentia-theme | localStorage | Remembering whether you chose the light or the dark theme | Until you clear it |
| plentia-idioma-aviso | localStorage | Remember we already offered you the other language once, so we don't offer it every time | Until you clear it |
| plentia-barra-cerrada | localStorage | Remember that you closed the bar at the bottom (“See what Plentia does for you”), so we don't show it again | Until you clear it |
| plentia-demo-lectura | localStorage | Remember that you have already tried reading one of your own invoices in the demo (one per browser is allowed) | Until you clear it |
| plentia-cookies-visto | localStorage | Remember you have already seen the notice on this page, so we don't repeat it | Until you clear it |
| sb-…-auth-token | localStorage | Keeping you signed in to your account | Until you sign out |
| plentia:web-scroll, plentia-periodo, plentia-marca, plentia-gastos-filtro, plentia-inicio, plentia-trimestre, plentia-demo-band, plentia:email-pendiente | sessionStorage | Not losing where you were, which period you were looking at or which filter you had while moving around the site or the dashboard | Until you close the tab |
None of these is used for advertising or to follow you across other sites. According to the cookie guide of the Spanish Data Protection Agency (May 2024), preferences chosen by the user themselves, such as language, and session and authentication ones fall outside article 22.2 because they are a service the user expressly requested. They are listed here anyway, which is what that same guide recommends.
None. Measured on 21/09/2026 in a fresh window with nothing stored, on the home page, on a subpage, on the English version, on the sign-in screen and in the demo: none of those screens requests anything from any domain other than Plentia's.
That day the four that were there were removed: the analytics of the company that hosts the site, the library that connects to the database — now served from Plentia, and not only for privacy: it is the one that handles sign-in, so bringing it in-house stops anyone injecting code into the screen where you type your password — and the two background paintings, which now live here too.
Plentia uses no analytics, no pixels, no advertising and no tool that follows you around other sites. If that ever changed, this page would change first.
The first time you open the site, a notice appears at the bottom with this same information and a button that says “Got it”. It is not a consent banner and it asks you for no permission: since there are no ads, no tracking and no third parties, there is nothing to authorise.
When you close it, a marker is saved in local storage so we don't repeat it, and that is all it does. It is the last row of the table above: plentia-cookies-visto.
From your browser settings, by clearing this site's data. If you clear the session you will have to sign in again.
